Sinus bleeds are weird things. I've got dermatitis (exceedingly dry skin) and that is somehow connected to sinus problems (yeah, I've lived with it for quite some time and it still doesn't make sense to me). Anyway, just to give you an idea, I was walking through a public restroom door and the pressure change caused by openning it set off a sinus bleed that lasted 15 minutes.Baraendur said:Dang dude. Do they know the cause of your dad's sinus bleed?
